Compliance Program

General Compliance PROGRAM

Project Description

The compliance program consists of five sub programs to help maintain the client’s overhead electric transmission system. ASEC has performed single pole replacements, total line clearance analysis, marker ball analysis, and structural integrity analysis on lines in Compliance Program’s system ranging from 69kV to 500kV. Design and analysis has also been performed on distribution and communication lines.

SCOPE

The programs include:

• Corrective Maintenance Program (CMP)- 450 projects worked.
• Request to Attach Program (R2A)- 120 unique projects worked.
• Pole Loading Program (PL)- 10 assessments completed.
• Aerial Lighting & Marking (ALM)- 50 group segments analyzed.
• Tie Line Assessments (TLAs)- 8 assessments completed.

Compliance (CMP)

Project Description

ASEC has been the primary consultant on this program over the last three years. The program consists of single pole replacements from wood to steel on structures from 69kV up to 230kV with distribution and communication underbuild. ASEC has completed design replacements on over four hundred and fifty wood poles and the work is on-going.

SCOPE

ASEC fields each structure, discusses the appropriate design path with the client, and then models the structures in PLS CADD. ASEC then creates construction ready packages for replacement.

OUTCOME

ASEC works on over one hundred and fifty unique replacement packages per year and works with client hand in hand to meet California’s regulatory compliance dates.

Request to Attach (R2A) 

Project Description

ASEC performs assessment of existing transmission poles for distribution under-build attachments for third party communication attachments. ASEC models the existing transmission, distribution, and communication connections to the subject pole and adds the new communication line for assessment on the structure utilizing the latest GO95 and client requirements. All PLS-CADD models are run using finite element analysis.

SCOPE

ASEC determines if the third party attachment causes any over stress in the structure and if it will have adequate clearances to ground and to other installations. ASEC transmits the findings to the client.

OUTCOME

ASEC works on over thirty unique assessments per year and works with the client hand in hand to approve or deny the requests. ASEC has worked on over 120 total R2As.

Tie Line Assessment (TLA)

Project Description

ASEC performs complete clearance evaluations of existing 69kV and 138kV lines. Based on the findings, ASEC develops construction packages and material lists to remediate the violations.

SCOPE

ASEC discusses the appropriate mitigation path with the client, and then models the mitigation plan in PLS-CADD. ASEC then creates construction ready packages for replacement.

OUTCOME

ASEC has analyzed eight line segments for SDG&E and has performed mitigation for the poles shown to be in violation of GO95 clearances.

Project Details

Date 2016 – Present

Pole Loading

Project Description

Complete analysis of 69kV and 138kV wood pole lines. All structural and clearance
violations are reported and remediation developed for each through PLS-CADD modeling and construction package and material list development.

SCOPE

ASEC discussed the appropriate mitigation path with the client, and then modeled the replacement structures in PLS-CADD. ASEC then created construction ready packages for replacement.

OUTCOME

ASEC has analyzed ten line segments for the client and has performed mitigation for the poles shown to be out of compliance (overloaded structure or clearance violation).

Date 2015 – Present

Aerial Lighting and marking (ALM)

Project Description

ASEC analyzed and reported spans with the client’s system that would require the addition of marker balls to meet FAA requirements. ASEC then designed and issued construction packages for marker ball additions on over eighty spans of 138kV, 230kV, and 500kV lines that involved lattice tower analysis and modification as well as a new tapered tubular pole design.

SCOPE

ASEC fielded each span, discussed the appropriate design path with the client, and then modeled the structures in PLS-CADD. ASEC then created construction ready packages for replacement.

OUTCOME

ASEC contributed to updating the client’s transmission line system by marking all spans over 200’ elevation, decreasing the client’s risk for accidents on lines over 200’ in elevation.

Date 2017-2018

Tower Organization

Project Description

The client has requested ASEC to help organize their 500kV Lattice Tower and Engineered Steel pole files. Each structure used in 500kV transmission line will have a database created to show the structure numbers, structure type, and drawing numbers. An interface was created to search for a structure number on a line and all the specific information would be populated for that structure.

SCOPE

ASEC performed this organizational work on 559 structures included with transmission lines TL50001, TL50002, TL50004. The database was programmed and created internally by ASEC engineers.

OUTCOME

ASEC created a pilot program that can be reproduced and used on other lines in SDG&E’s system. ASEC has the ability to organize all of the client’s transmission line circuits from 69kV to 500kV in this manner.
